I have a pool with 2 hosts and 12 VMs. The VMs are on an attached SR. Currently, the version of XenServer is 6.0.2 and I need to upgrade to 7.1 but I was wondering what's the best way to do that considering I'm not an expert. I have 2 choices:
- Use Rolling pool upgrade
- Install as new the version 7.1
Citrix Upgrade Planning from Xenapp 6 or 6.5 to 7.6 10:09 AM. The upgrade wizard will remove the 6.5 worker from the farm, uninstall the 6.5 software and install the 7.6 VDA while placing the server into the 7.6 site. Yes, although it is experimental. The commands used to gather the farm, policy and application settings from XenApp 6.5. XenServer hosts must be running at least version 5.6 in order to upgrade directly to version 6.2.0. For example, to upgrade from version 5.5 to version 6.2.0, you must first upgrade version 5.5 to version 5.6 (or to version 5.6 Feature Pack 1 or 5.6 Service Pack 2), and then upgrade version 5.6 (or version 5.6 Feature Pack 1 or 5.6 Service Pack 2) to version 6.2.0, and so on.
For both, I need some advice, so if I use

Rolling pool upgrade is this method stable enough to do this operation from 6.0.2 to 7.1? anyone had experience with that?
Install as new the version 7.1, in this case, I would proceed in this way:
- shut down all VMs
- backup all VMs information with
xe pool-dump-database file-name=backupPool
- detach server number one from the original pool
- detach the SR from the original pool
- install from scratch XenServer 7.1 on server number one
- create a new pool with only server number one on it
- attach the SR to the new pool
- import the backup taken at point 2
- now if everything is ok, I should be able to start the VMs and start again from point 5 with the server number 2
what's the best and safest way to proceed?
Thanks a lot

I tested it few months ago, it was upgrade from 6.2 to 7.1 by rolling pool upgrade and I did not had any issues.
I did it in steps: 6.2 > 6.5 > 7.0 > 7.1
About my upgrade - it was cluster with three nodes.I did upgrade by webserver with all necessary files that was set up on my workstation. Steps you mentioned are OK.
Prepare first and dont forget about all necessary patches that was released by Citrix along the way.
- read necessary documents on upgrade,
- backup settings
- proceed
